I have the bustle pattern I used for my wedding dress.... if you can wait a few weeks, I can trace out the pattern, and a skirt that will fit over it. You might want a bustle pad as well just to give it "omff!"

It's the one from Truly Victorian, not the grand, but just the caged upper part. If you can draft your own skirting, I can get that done a LOT faster and can drop it in the mail sooner. Of course I'll have to photocopy instructions too huh?
